YARN BOBBIN Filed July 2, 1942 humana-.2o. 194s l Claim.

A further object'constitutes the provision of a bobbin which ls made ofa ilexible material and comprises an elongated body member having asemi-circular cut out portion at one end and a circular opening at theother end there 'being a slit between the opening and the edge oftheother end permitting insertion or unwinding of the yarn by laterallyspringing the terminal portions of said other end.

With these and other objects in view which will become apparent from aperusal of the inventlon the latter comprises the means described in thefollowing specication, particularly pointed out in the claim forming apart thereof and'illus trated in the accompanying drawing, in which Fig.1 is a front view of the bobbin constructed in. accordance with myinvention,

Fig. 2 is a section on line 2-2 oi' Fig. 1. and

Fig. 3 is a bottom plan view.

Referring to the drawing lil designates an elongated body member made ofcellulose acetate material or any other material which has springy orresilient properties.

As shown the member llhas a semi-circular cut-out portion H at the endportion I2 and the other end ill is semi-circular. A. circular openingil is concentrically arranged at the end I8 and a slit- It between theopening Il and the terminal edge ofthe end I3 defines two prongs I8 andi1"which may be separated by flexing.

Upon cessation oi? the pressure the prongs resume normal position.

It is'evident that the yarn is wound around the body member by being4threaded through theY slit I5, and wound on the edge oi the cut outportion Il, again threaded through the slit il and wound on the edge Iland this continued until the entire` yarn is wound on the member.

If desired diilerently colored yarns may be wound on the member I0 or aplurality of members may be -employed each having yarn of difarticlesare 4free end and defining a circular opening, said prong ends being inthe same plane as said body member and separable by flexing in a pianeat right angles to the plane of said body member and at the longitudinalcenter thereof and means at the other end of said body memberforreceiving the turns of the yarn coiled around the body .portion throughthe opening. s aid prongs controlling the winding and unwlnding of thecoil.
